RADIO APPARATUS.

Application filed April 18, 1925.

My invention relates to loud speaking devices particularly adapted for use in combination with radio receiving apparatus for reproducing intelligence.

l-Ieretotore it has been customary to use horns or megaphone shaped loud speaking devices, some of which have manually operat1v'e means :tor EIClJLlStIDg and regulating the volume or intensity of reproduced radiocast performances. Radio apparatus is placed often in the best equipped room or part'ot a home and it is very desi able that the apparatus present an attractive appearance. Furthermore, house-wives are es pecially desirous that radio apparatus be constructed so that it is unadapted to collect dust and will not interfere with cleaning and dusting the home and frurniture. Also for economical reasons it is advantageous to combine necessary. and ornamental articles of home furniture with radio apparatus for the reason that by so doing the expense of radio equipment can be materially reduced as the need of purchasing certain required articles for the home may be eliminated.

The objects of myinvention are to provide a simple, effective, practical, economical and highly desirable combination lamp and radio loud speaking device; to provide convenient and efficient manually operative means whereby the intensity and volume of sound waves may be controlled; and to provide a loud speaking device particularly adapted to deflect. sound waves with uniform volume and. intensity in all horizontal directions. v

My invention consists in providing a combination lamp and loud speaking device, the shade of said lamp being utilized as sound wave deflector; in providing manually operative means for vertically adjusting said shade relative tothe loud speaking unit; in providing an outwardly tapered and upwardly extending tube connected with the sound exit of said unit having vertical supports attached thereto; in providing a vertical .rod having said lamp shade fixed to its upper end and having its lower end adjustably secured in a ring integral with said supports; and in providing a casing completely containing said unit and said supports.

My invention further consist in the combination, arrangement, location and details of construction of the parts, as herein setforth and claimed.

In the drawing: Fig. l is a side elevation of the invention; Fig. 2 is a vertical section of the same taken on a line corresponding to 2-2 in Fig. l; and

Fig. 3 is a plan view of the invention.

In the preferred construction of my invention I provide combination lamp and radio loud speaking device 1. Upwardly extending integrally connected supports 2 and 3, respectively, are fixed to usual loud speaking unit 1 by screws at and 5. The up per portions 6 and 7 respectively, or supports 2 and 8 are curved outwardly and extend inwardly and are integrally connected with ring 8 having vertical hole 9 therein, whereby the vertical rod 8' is adjustably received therein. The rod is retained in a vertically adjusted position by thumb screw 10 threaded in ring 8 and adapted, when screwed inwardly, to trictionally engage the rod. The upper end of rod 8 has lamp cluster 11 suitably secured thereto whereby sockets 12 and 13 are retained in position for the purpose of receiving lamps 14 and 15 connected to suitable outside source of electric supply as by conductors 16 and 17 (shown broken away) which, preferably, extend parallel. with stem 18 of device 1 and through base 19 of vase 19 which may be of any desired form. The height of "ass 19 is sufficient to conceal unit 1 and supports 2 and 3 from ordinary visual observation, whereby the invention presents an attractive appearance.

Usual conductors 20 and 21 are connected to unit 1 and are received through holes 22 and 23, respectively, in base 19 of vase 19 whereby the loudspeaking unit may be .7

conveniently connected in the usual man nor to a radio receiving set (not shown).

Lamp shade 2% is concavo-convexo formed with the outer surface 25 extending d0wnwardly and is suitably fixed to upper end 26 of rod 8 whereby the sound waves which issue from unit 1 travel upwardly through an outwardly tapered sound tube 27, (having its lower end connected to sound wave exit tube 28 of unit 1) and then are deflected downwardly by the concave inner surface 24 of shade 2d and then are free to travel outwardly in all horizontal directions with uniform intensity and volume.

It is apparent that I have invented a simple and efficient combination lamp and loud speaking device which may be made in ill) Ill)

various and attractive forms and which is especially adapted to permit variation of the intensity, volume and the quality of the sound waves issuing from unit 1, as by merely unscrewing thumb screw 10 and elevating and lowering rod 8' having shade 24 fixed to its upper end, whereby the distance of shade 24 from the upper end of tube 27 is controlled which effects the volume and tone of a reproduced radio-cast performance.

An advantage of my invention is that an inexpensive and non-adjustable unit 1 may be used in my invention and by simply adjusting the height of shade 2% considerable and highly desirable variations in the volume and tone quality of the sound waves can be conveniently accomplished.

lVhile I have chosen to illustrate the form and construction of my invention by the herein drawings and explanations of the same, it is understood that my invention resides in the combination, arrangement of parts and in the details of construction, as hereinafter claimed. It is further understood that changes in the precise embodiment of my invention can be made within the scope of what is claimed. without departing from the spirit thereof, as for instance, the shape of shade 2st and vase 19 may be varied considerably, as may be apparent to those familiar with the art.

What I claim as new and desire to secure by Letters Patent is:

1. In a device of the class described, a sound wave reproducing unit having a sound wave exit, a pair of spaced apart supports fixed to said unit, a vertical rod detachably secured to the upper ends of said supports, a casing concealing said unit and said supports, an outwardly tapered tube secured to said unit adjacent said exit and extending upwardly, and a concavo-convexo lamp shade having its concave surface fixed to the upper end of said rod and having its outer rim extending downwardly, whereby sound waves issuing from said tapered tube are adapted to be directed downwardly.

2. In a device of the class described, a sound Wave reproducing unit having a sound 1,619,407. Q3133! AWbMtEf-LE SQF";

wave exit, a support fixed to said unit, a rod secured to the upper end of said support, a casing concealing said unit and said support, an upwardly extending tube secured to said unit adjacent said exit, and a concave deflector having its concave surface fixed to the upper end of said rod and having its outer rim extending downwardly, whereby sound waves issuing from said exit are adapted to be deflected downwardly.

3. In a device of the class described, a sound wave reproducing unit, apair of spaced apart vertical supports fixed to said unit, a vertical rod adjustably connected with the upper ends of said supports, a vase concealing said unit and said supports, an outwardly tapered and vertically extending tube connected with said unit and a concavoconvexo sound deflector having its concave surface fixed to the upper end of said rod, whereby sound waves issuing from said tapered tube are adapted to be deflected downwardly with uniform volume.

at. In a device of the class described, a sound wave reproducing unit having a sound wave exit, a pair of spaced apart vertical supports fixed to said unit, a rod adjustably connected with the upper ends of said supports, a vase concealing said unit and said supports, an outwardly tapered tube secured to said unit and in registering position with said exit and extending vertically, and a concavo-convexo lamp shade fixed to said rod and spaced apart from said tube.

5. In a device of the class described, a sound wave reproducing unit, a pair of spaced apart supports fixed to said unit, a vertical rod positioned intermediate and ad justably connected with said supports, a vase containing said unit and said supports, a sound exit tube fixed to said unit, an out wardly tapered and upwardly extending sound tube connected with first said tube, and a concavo-convexo sound deflector having its concave surface fixed to the upper end of said rod, whereby'sound waves issuing from said tapered tube are adapted to be de flected downwardly with uniform volume.
